Description
Technical field
The utility model relates to a kind of novel half steel light load-carrying radial-ply tyre tyre bead.
Background technology
The carcass of half steel light load-carrying radial-ply tyre is comprised of three layers of fiber cord conventionally, at tyre bead place, by two layers of anti-package and one deck positive closure cord, formed, positive closure end points is free point, the free end points of cord is structure design defect, stressed contrary due to positive closure and anti-package cord, the quality problems that produce delamination between positive envelope and anti-package face account for 50% of whole damaged tyres.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned defect, and a kind of design defect of carcass ply at the free end points of tyre bead place positive closure cord that solved is provided, and reduces the half steel light load-carrying radial-ply tyre tyre bead of damaged tyres rate.
To achieve these goals, the half steel light load-carrying radial-ply tyre tyre bead of the utility model design, comprise bead bundle, the bottom outside of described bead bundle is coated with the wear-resisting glue of tyre bead, described bead bundle top is provided with triangle rubber, the wear-resisting glue of described tyre bead inner side is provided with rectangle steel wire ring, and the first half of described rectangle steel wire ring is coated with casingply, and the first half of described bead bundle is by being coated with successively carcass fibres cord and carcass inner seal layer outside interior.
In technique scheme, the wear-resisting glue of tyre bead is connected with sidewall rubber.
The utility model tyre bead is provided with rectangular wire coil structures in the wear-resisting glue of tyre bead inner side, the little bead coil of partially flat rectangle becomes anti-package design by the design of positive closure carcass, thereby solved the design defect of carcass ply at the free end points of tyre bead place positive closure cord, reduced damaged tyres rate.
Accompanying drawing explanation
Fig. 1 is integral structure schematic diagram of the present utility model;
In figure: 1-bead bundle; The wear-resisting glue of 2-tyre bead; 3-triangle rubber; 4-rectangle steel wire ring; 5-casingply; 6-carcass fibres cord; 7-carcass inner seal layer; 8-sidewall rubber.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Half steel light load-carrying radial-ply tyre tyre bead as shown in Figure 1, comprise bead bundle 1, the bottom outside of bead bundle 1 is coated with the wear-resisting glue 2 of tyre bead, bead bundle 1 top is provided with triangle rubber 3, the wear-resisting glue of tyre bead 2 inner sides are provided with rectangle steel wire ring 4, the first half of rectangle steel wire ring 4 is coated with casingply 5, and the first half of bead bundle 1 is by being coated with successively carcass fibres cord 6 and carcass inner seal layer 7 outside interior.The wear-resisting glue 2 of tyre bead is connected with sidewall rubber 8.
The utility model tyre bead is provided with rectangle steel wire ring 4 in the inner side of the wear-resisting glue 2 of tyre bead, the little bead coil of partially flat rectangle becomes anti-package design by the design of positive closure carcass, thereby solved the design defect of the free end points of carcass fibres cord 6 place's positive closure cord, greatly reduce damaged tyres rate, improve tire quality, extended the service life of tire.
The content not being described in detail in this specification sheets belongs to the known prior art of professional and technical personnel in the field.
